how do you do a quadratic equation without a b value?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "All quadratics have a b value but sometimes the b value is zero and, in fact, sometimes the c value or a a value is zero. If the a value is zero, I believe that it ceases to be a quadratic.
\n" ); document.write( "In other words:
\n" ); document.write( "Ax^2+C=0 can be written as:\r
\n" ); document.write( "\n" ); document.write( "Ax^2+0x+C=0 solve using the quadratic formula
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"x+=+%280+%2B-+sqrt%28+0-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
